About DPVM Databases

The DPVM database consists of a series of device mapping entries. Each entry consists of a device
pWWN/nWWN assignment along with the dynamic VSAN to be assigned. You can configure a
maximum of 16,000 DPVM entries in the DPVM database. This database is global to the whole switch
(and fabric) and is not maintained for each VSAN.
The DPVM feature uses three databases to accept and implement configurations.

Changes to the DPVM config database are not reflected in the active DPVM database until you activate
the DPVM config database. Changes to the DPVM pending database are not reflected in the
config/active DPVM database until you commit the DPVM pending database. This database structure
allows you to create multiple entries, review changes, and let the DPVM config and pending databases
take effect.

Configuring DPVM Config and Pending Databases

To create and populate the DPVM config and pending databases, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# dpvm database
switch(config-dpvm-db)#
switch(config)# no dpvm database
Step 3
switch(config-dpvm-db)# pwwn
12:33:56:78:90:12:34:56 vsan 100
switch(config-dpvm-db)# no pwwn
12:33:56:78:90:12:34:56 vsan 101
Step 4
switch(config-dpvm-db)# nwwn
14:21:30:12:63:39:72:81 vsan 101
switch(config-dpvm-db)# no nwwn
14:21:30:12:63:39:72:80 vsan 101
